PURPOSE: A vibration device is provided to improve the horizontal vibration efficiency of a vibrator by floating and supporting the vibration with only the elastic member. CONSTITUTION: A case(110) provides a component mounting space. A coil(120) is arranged on the inner bottom of a lower case(112). A vibrator(130) horizontally moves by an electromagnetic force generated by the interaction with the coil. The vibrator includes a permanent magnet(131) and a weight(132). An elastic member(140) is formed on both sides of the vibrator and elastically supports the vibrator.
